2 Corinthians 9:11-13

He shall multiply what you have in Him, your seed and your fruit, and the perfection from which they flow. Those riches grow for those who are simple and honest in heart, and the greatest possession is that gratitude which we feel to God, and that is the secret of this fund which I have organised. It does not merely fill the want of churches elsewhere, it is the sure and abounding fruit of great gratitude to God in our midst. Those receiving it will praise God the more joyfully when they realise the test which this contribution has put you to, when they see your obedience and common acknowledgement of the gospel of the Christ, when they feel the simplicity of heart with which the gift is made to themselves and which is present also in all your dealings towards others
